ELECTRONIC TEMPERATURE CONTROLS - The electronic temperature control (ETC) supplied byTankless Inc.is a Ranco product at a cost of $100. It measures the temperature of the inboundwater and turns on the heater if the inbound water temperature is less than the “temperature turn off” temperature less the difference. For example, if you have the temperature set at 180 and the difference at 1 the heater will turn on if the temperature coming in is less than 179 degrees. Click here for more details and to order.

MIXING VALVES - We recommend a 3/4" mixing valve (MVH) at a cost of $100 supplied by Honeywell for normal applications. It is easily set and monitors the temperature by mixing more or less cold water with the hot water from the heater. It can be set from 75 to 145 degrees and allows a maximum flow of 12 GPM. If you need more flow thru the system we have a 1" model available for $200 that allows a maximum flow of 16 GPM and a 1 1/4" model for $575 that flows a maximum of 30 GPM. Other models are available that allow different temperature ranges. Click here for more details and to order.

The normal switch(PS1) shuts off at 3 PSI is $55. The (PS2) shuts off at varying levels set by the customer costs $205. The (PS3) shuts off at 100 PSI is $160.
